Hue Control On GE 15CL100

[Electronic M]

GE's circuit is a resonator not an oscillator. It works like a 3.58Mc tuning fork that gets struck each chroma sync burst and will hold the note for multiple bursts should any be missing.

However the chroma oscillator is not something that typically drifts in a way that requires the hue control to need adjustment....Back then broadcast equipment setup was subjective and prone to drift, and network feeds and some reception conditions were prone to distort the color signal into needing hue correction....It was not a good choice put that control on the back IMO.
